Possible Causes
Worn rear tub bearings on UniMac outer tub, Failed tub seal allowing water into bearings, Damaged drum spider shaft, Corroded bearing housing
How to Fix / Troubleshooting
Safety first: Disconnect power before disassembling the cabinet or tub.
- Confirm bearing noise: Spin the empty drum by hand. A rough, grinding, or roaring sound indicates bearing wear.
- Check for play: Lift the inner drum up and down at the front. Excessive movement suggests bearing or spider failure.
- Plan for major repair: Bearing replacement on UniMac front-load washers typically requires removing the drum and splitting the outer tub. This is a complex repair requiring special tools.
- Replace tub assembly: Many technicians replace the complete rear tub or outer tub assembly (with bearings installed) rather than pressing in new bearings. Consider professional service for this repair.
